When lithium-ion battery fires threaten your facility, every second counts. The EV Fire Robot throwing water from fourobot delivers enterprise-grade firefighting power in a compact, remotely controlled platform. With 16 hours maximum working duration, a lightweight 50kg design, and rapid 20-day production cycle for 1–10 units, this robot tackles thermal runaway with precision water mist technology. Backed by 10 years of manufacturing expertise, CE/ISO/TAF certifications, and 100 units ready in stock, you get reliable performance when traditional methods fall short. Its 4m³ coverage area and 0.4L/s flow rate cool battery casings effectively while keeping your team safe from toxic HF gas exposure.

Electric vehicle fires display one of a kind challenges that customary firefighting cannot address securely. Warm runaway in lithium-ion batteries creates extraordinary heat—often surpassing 1,000°C—and discharges exceedingly harmful hydrogen fluoride gas. Human firefighters confront life-threatening dangers drawing nearer these blazes.
You require hardware that enters perilous zones without gambling lives. The item navigates where people cannot. Its compact 78×48×21cm impression slips through limit stopping carport passageways and low-clearance spaces. The all-terrain flame-resistant elastic crawler keeps up footing on damp surfaces whereas climbing 40° inclines.
Remote operation keeps your personnel at safe distances up to 200 meters away. The IP65 waterproof rating ensures reliability even when drenched in suppression water or exposed to chemical runoff.
Battery fires require sustained cooling over hours—not just quick water bursts. This robot delivers continuous operation for up to 16 hours without recharging. Its dedicated self-cooling system prevents equipment failure during prolonged deployments.
The water mist system operates at 0.8 MPa pressure, producing 60μm particles that penetrate battery casings more effectively than solid streams. This cooling approach manages heat flux and prevents fire spread to adjacent vehicles—your primary goal in densely packed charging facilities or underground garages.
Transportation flexibility matters when fires strike. At just 50kg, two personnel can rapidly deploy the unit from fire truck cabinets. Your response team saves critical minutes during the golden period of fire suppression.

Versatile Deployment Options
Your facility gets multiple configuration choices. The standard self-cooling system handles most scenarios. Add the optional Otter-X Detachable EV Cooling Module when you need dual-extinguisher capability with potassium oxide for aggressive thermal events.
Built for Demanding Environments
The electric servo motor provides precise control in confined spaces. Ground clearance of 4cm allows access under most vehicles. The turning-in-place capability lets the robot maneuver in tight corners where traditional equipment cannot reach.
Rapid Response Capability
With 100 units maintained in stock at our China warehouse, you avoid lengthy procurement delays. Production cycles of just 20 days for orders of 1–10 units mean your facility can scale protection quickly. Our 5×12 hour response time ensures questions get answered when you need support.
Flexible Logistics Solutions
We offer air, sea, and land shipping options to match your urgency and budget requirements. Whether you need emergency deployment or planned infrastructure upgrades, transportation adapts to your timeline.
Customization for Local Requirements
ODM/OEM services allow function modifications based on your country's regulations or specific operational needs. Different fire scenarios demand tailored solutions—we work with your team to configure the right setup.

Underground Parking Facilities
Low ceilings and restricted ventilation create deadly conditions when EVs catch fire. The EV Fire Robot throwing water navigates these environments autonomously, delivering cooling mist directly to battery compartments while smoke management systems extract toxic gases. You protect property and create safe egress paths for trapped personnel.
High-Density Charging Stations
Logistics hubs and fleet charging facilities concentrate fire risk in small areas. Early detection paired with immediate robotic response prevents single-vehicle incidents from cascading into catastrophic losses. The robot patrols charging bays and responds within seconds of thermal alerts.
Highway Tunnel Recovery Operations
Tunnel fires combine extreme temperatures with zero visibility. Traditional firefighting requires dangerous human entry into these zones. Remote-controlled water-throwing robots establish cooling curtains that reduce heat intensity, allowing recovery teams to approach safely once thermal flux drops to manageable levels.
Residential Parking Areas
Urban residential complexes increasingly include EV charging infrastructure. When fires occur in these settings, evacuation challenges and proximity to living spaces amplify risks. Compact fire robots deploy quickly from building security stations, providing immediate intervention before fire services arrive.
Traditional fire hoses deliver large water volumes that may not effectively cool battery internals. The EV Fire Robot throwing water uses specialized mist technology that creates 60-micron water particles. These tiny droplets:
The 0.8 MPa working pressure balances penetration power with equipment durability. Higher pressures might damage robot components during extended operations. This carefully calibrated system delivers sustained performance throughout the critical cooling period.
The 4m³ coverage area focuses water exactly where thermal activity concentrates. Unlike wide-spray approaches that waste water, targeted mist delivery maximizes cooling efficiency per liter deployed.

Q:Can an product permanently extinguish lithium battery fires?
A:The robot's primary function is heat management—not complete extinguishment. It cools battery casings to prevent fire propagation to adjacent cells and vehicles. Complete extinguishment occurs after the battery's chemical energy depletes, which may take hours. Continuous cooling prevents re-ignition during this period.
Q:What maximum water pressure can the chassis handle without losing traction?
A:Standard industrial units safely handle 1.0 to 1.6 MPa without compromising traction or stability. Our unit operates at 0.8 MPa, providing an optimal balance between effective cooling spray and mechanical reliability during extended deployments.
Q:How does the robot handle toxic runoff from EV fires?
A:The robot features corrosion-resistant construction to withstand acidic water produced during lithium-ion battery fires. While the robot itself doesn't collect runoff, its design allows operation in conjunction with containment systems that facility managers deploy around fire zones.
Q:Is the water throw pattern adjustable during operations?
A:Yes. Remote operators toggle between solid streams for deep penetration into battery compartments and fog patterns for smoke scrubbing and area cooling. This flexibility allows tactical response adjustment as fire conditions evolve.
Q:What happens if wireless signal is lost during operation?
A:Professional-grade units include failsafe protocols. The robot maintains its last commanded position and continues water deployment until signal restoration. Some configurations offer automatic return-to-base functions when control loss exceeds predetermined timeframes.
Q:How long does deployment take from storage to active firefighting?
A:Two trained personnel can deploy the 50kg unit in under two minutes. The compact size allows storage in standard fire truck cabinets or facility equipment rooms, eliminating transport delays to the fire scene.
Q:Can the robot operate in extreme temperatures?
A:Standard configuration works from -20°C to +60°C. Optional low-temperature batteries extend the lower range to -40°C for facilities in arctic climates or specialized cold-storage applications.
Q:What maintenance requirements does the robot have?
A:Regular maintenance includes crawler inspection, battery charging cycles, and self-cooling system testing. Our 1-year warranty covers manufacturing defects, and global local agent support ensures timely maintenance assistance.
